Hey, I work on Apache Hive project which was using Antlr 3.0.1 till now and its working great. Thank you guys. Now I am trying to port it to 3.4 and I see antlr returning incorrect parse tree in 3.4 which used to be correct in 3.0.1. I tested with 3.1 and thats returning correct parse tree too. Grammar is defined here:
https://svn.apache.org/repos/asf/hive/trunk/ql/src/java/org/apache/hadoop/hive/ql/parse/Hive.g and test program is: insert overwrite table alter3 partition (pCol1='test_part:', pcol2='test_part:') select col1 from alter3_src ; In 3.0.1 and 3.1 I get following parse tree which is correct (nil(TOK_QUERY (TOK_FROM(TOK_TABREF (TOK_TABNAME(alter3_src))))(TOK_INSERT (TOK_DESTINATION(TOK_TAB(TOK_TABNAME(alter3))(TOK_PARTSPEC(TOK_PARTVAL(pCol1)('test_part:'))(TOK_PARTVAL(pcol2)('test_part:')))))(TOK_SELECT(TOK_SELEXPR(TOK_TABLE_OR_COL(col1))))))(null)) whereas in 3.4 I get following parse tree which is incomplete and thus incorrect (nil(TOK_QUERY (TOK_FROM (TOK_TABREF (TOK_TABNAME(alter3_src))))(TOK_INSERT (TOK_DESTINATION(TOK_TAB))(TOK_SELECT (TOK_SELEXPR (TOK_TABLE_OR_COL(col1))))))(<EOF>)) Is there something I should keep in mind while trying to upgrade to 3.4. I was not able to test with 3.2 or 3.3 because of a different problem in ant plugin of antlr because of which I was not able to build. It was failing following stacktrace: Exception in thread "main" java.lang.NoClassDefFoundError: antlr/RecognitionException [java] at org.antlr.Tool.getRootGrammar(Tool.java:551) [java] at org.antlr.Tool.process(Tool.java:422) [java] at org.antlr.Tool.main(Tool.java:91) [java] Caused by: java.lang.ClassNotFoundException: antlr.RecognitionException I will be happy to provide any more information which will help figure out this issue.
